Claims. (Cl. 285-71) The present invention relates to suction cleanersand more particularly to a device for detachably connecting a dirt bagto the discharge nozzle of a suction cleaner.

An object ofthe invention is to-provide a new and improved-suctioncleaner. Another object is to provide a detachable connection betweenthe discharge nozzle of a suction cleaner and the dirt receiving bag. Afurther object is to provide a detachable connection between a,discharge nozzle of a suction cleaner and the dirt bag, the jointbetween these parts being substantially fluid type. Another object is toprovide a detachable connecting device'that is permanently mounted onthe cleaner discharge nozzle, whereby the connecting device is notmislaid and the dirt bag can be of inexpensive manufacture. Other objects and advantages of the invention will become apparent from thefollowing description and attached drawings wherein:

Figure 1 is a side elevational view of the suction cleaner showing oneembodiment of the invention; 4 r I Figure'z is a section of theconnecting-device between the discharge nozzle and'the dirt bag;

Figure 4 is anexploded perspective view of another embodiment a of theinvention showing the discharge nozzle and dirt bag disconnected;

Figure 5 is an exploded perspective view of still another embodiment ofthe invention showing the discharge nozzle and dirt bag disconnected,and

Figure 6 is a section of the connecting device illustrated in Figure 5and showing the dirt bag connected to the cleaner discharge nozzle.

Figures 1 to 3 disclose one embodiment of the invention in'asuctioncleaner comprising a cleaner body It including a nozzle ll communicatingwith an unshown fan chamber connected to an exhaust passageway whichterminates in a flange l2. An unshown motor is supported on the body if)and is enclosed in a motor housing I3, the motor driving an unshown fanin the fan chamher to draw dirt-laden-air from the surface being cleanedthrough the nozzle II and to discharge is a bag adaptor It comprisingstationary and movable members l9 and 20, respectively, the former beingprovided with an opening 2| which communicates with the exhaustpassageway when the member 19 is rigidly attached by means of a pair ofnut and bolt connections 22 to the exhaust flange l2 of the cleaner bodyID. The movable member 20is pivotally mounted at 23 on the stationarymember I9 and is provided with a discharge nozzle 24 having a reduceddiameter to form an annular shoulder 25, and the discharge nozzle 24communicates with the opening 2| by means of a flexible bellows 26.

Permanently mounted on the discharge nozzle 24 is a cord anchoring means21 forming part of the bag connecting device, and includes a stud 28which is rigidly mounted on and projects outwardly from the dischargenozzle 24. Rigidly secured to the outer end of the stud 28 is a rubberor plastic disc 29 which is provided along its inner surface with ametal apron 30 having a flared periphery 3|, and the apron 30 is spacedfrom the exterior surface of the discharge nozzle 24 to admittherebetween the mouth-32 of a dirt bag 33 and a cord 34 which may be ofresilient material.

The dirt bag 33 is of flexible dirt filtering material and includes atits lower end the constricted open mouth 32, and is provided at itsupper end with an unshown dirt emptying opening closed by a removableclamp, and extending from the bag mouth 32 longitudinally the length ofthe bag are diametrically opposed pleats35. The upper end of the bag 33is supported by the handle l6, and movement of the latter causes thelower end of the bag and discharge nozzle 24 to pivot about the axis 23.A marginal opening 36 is provided in the upper wall of the bag mouth 32midway between the opposed pleats 35 and the inner portion 31 of theopening is reinforced by a member 38 rigidly mounted on the bag mouth byrivets 39, and permanently attached to the member 38 is one end 40 ofthe cord 34.

When it is desired to connect the bag 33 to the cleaner body H), the bagmouth 32 is telescoped about the discharge nozzle 24 with the opening 36in register with the stud 28 and the lower marginal edge 4| of the bagmouth abuts the shoulder 25. The cord 34 is then wrapped around the bamouth 32 to squeeze the latter tightly about the discharge nozzle 24 insubstantially air-tight relation, and the free end 42 of the cord iswrapped about the stud 28 between the bag mouth '32 and the apron 30 inorder to hold the cord tightly about the bag mouth and retain the latteron the discharge nozzle 24. Since the cord anchoring means 27 ispermanently attached on the discharge nozzle 24 and the cord 34 issecured to the bag 33, a connecting device is provided which preventsdisconnection of the bag 33 from the discharge nozzle 26 under the forceof the dirtladen air stream exhausted from the fan chamberagainst theinterior surface of the bag. The stud 28 acts as a pilot to position thebag'33 so that the bag pleats 35 are disposed in planes substantiallyparallel to the direction of handle movement whereby when the bag isinflated, the pleats will unfold to increase the bag size in oppositedirections transverse to the direction ofv handle movement to preventthe handle it from interfering with the inflated bag.

Th connecting device shown in Figure 4' issimilar to that described inconnection with Figures 1 to 3 with the exception that the apron 45 onthe cord anchoring means 46 is provided with a tap 41 to which one end48 of a cord 49 is permanently attached, and the mouth 50 of the bag isprovided with a marginal opening 52 which is placed' in register-withthe stud 2B.

In order to connect the bag 5| to the cleaner, the bag mouth Si istelescoped-about the discharge nozzle 24 with the opening, 52' inregister with the stud 28 to properly position the bag pleats 54 withrespect to the cleaner handle it. Thereafter the cord 49 is Wrappedaround the bag mouth to squeeze the latter against the discharge nozzle24 in substantially air-tight relation, and the free end 55 of the cord49 is wrapped about the stud 28. between the apron 45 and the bag mouth59 to hold the bag on the discharge nozzle 24.

Figures 5 and 6 disclose another embodiment of the invention comprisinga'bag adaptor 68- comprising a stationary member 6 i to which a memher 62' is pivotally connected at 63, the member 6! having an opening 64which communicates with the exhaust passageway when the member isdetachably mounted on the cleaner body it.

The movable member 62 is; provided with. a discharge nozzle 55 having anannular shoulder i and is connected to the opening 6:? by ailexiblebellows Eii'i. The. bag connecting device includes a cord anchoringmeans lit and a pilot l l, the latter being rigidly mounted on andprojecting; from the discharge nozzle- 65 to; receive an opening 12spaced from the marginal edge #3 of the mouth M of a bag 15. The. cordanchoring means includes a member'lfi rigidly secured to the free end ofa resilient. metal bracket ."i having its opposite end permanentlymounted byrivets l8 ina depressed wall 19 of the discharge nozzle 55,The member 16 has aport 86 adapted to be received by the pilot 1], and,is also provided with an annular groove- 8! to receive a cord 32. oneend 8.3 ofv which is permanently secured tothe member 62 In order toconnect the bag 'l5to the cleaner body, the bag mouth 1.4 is telescopedover the discharge nozzle 65 so that the pilot ll projects through theopening 12, whereby the bag pleats 84 are properly positioned withrespect to the cleaner handle. The resilient bracket ll is thendepressed causing the pilot H to enter the port 86 in the member 16, andthe cord 82 is wound about the bag mouth M to gather the latter andsqueeze it about the discharge nozzle in substantially air tightrelation, thereafter the free. end 85 of the cord is wrapped in thegroove, 3!, to hold the cord tightly about the bag mouth and retain thelatter on the discharge nozzle 85. When it is .de-

sired to disconnect the bag, the free end of. the cord 82 is removedfrom the a-nnular roove 8!:

and unwound from about the bag mouth 74 the Wall of said bag mouth beingdisposed between the discharge nozzle and said resiliently supportedcord anchoring means, and a flexible cord havin one end permanentlyattached to said cord anchoring means, said cord being of sufficientlength to be removably wound about the circumferential exterior of saidbag mouth to force the latter into engagement with the discharge nozzleand to depress said resiliently mounted cord anchoring means against thebag mouth, the other end of said cordbeing removably secured to saidcord anchoring means on said resilientmember to retain the bag on thedischarge nozzle.
